JACOB KUENZEL, OF NEVARK, OHIO,

IMPROVEW ENT IN FLOWS.

Specification forming part of Letters Patent No. E5L229, dated May 2G, 1874 application filed April 17, 1874.-

To all whom it may concern:

Be it known that I, JACOB KUENZEL, of city of Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in the Construction of Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specilication.

My invention relates to improvements in mold-board plows, in which those parts which are subject to greatest wear and liability to be broken are made in separate pieces, so that when such parts are broken or worn they can be readily removed and replaced by new pieces at small cost; and it consists in connecting said pieces together, and to an under casting or saddle, as hereinafter described, so as to form a strong and substantial plow.

In the drawings, Figure l is a view of the casting or saddle. Figs. 2 and 3 are opposite side elevations of the plow with the pieces all attached, and Figs. 4 and 5 are det-ail views of l the share and removable point.

a is a casting or saddle, which carries the several pieces. It has the wings a1 a2, corresponding to the mold-board and land-side of a plow, which are joined together by the hori- Zonta-l piece a3, forming a strong and substantial base, to which is bolted the standard of the plow, and the several pieces hereinafter described. a4 is a half-mortise formed in the front end of the saddle a, having the sides a5 a6. The front end of the saddle is made blunt and beveled by the faces a7 a8. a9 is a crossinortise formed in the land-side a2, and connects with the mortise a4. b1 b2 are holes through which to pass the necessary bolts for securing the several pieces to the saddle. c is the share. It reaches high on the moldboard, and has the portion c2 bent over the colteredge of the plow, so as to forni the front section of 'the land-side. It is cut away, as shown in Fig. 4, so as to forrn the triangular point c3 and edge c1. When the share is bent over the crown or colter-edge of the saddle, it closes in the -halfmortise a4, and forms a complete sheath or mortise for the recep tion of the shank of the point, hereinafter dcscribed. cl is the rear' land-side plate. e is the point. It has the triangular shank el, which has the side e2 beveled or iattened to correspond to the side a5 of the saddle. The shank is so attached to the point as to leave on said point the square shoulder e3, and on the under side rounded or beveled shoulders e* e5, which tit the faces a7 and a8 of the saddle, and it is provided with the side inortisc c6 and cross-mortise el. f is a key which iits into the niortises e9 and a7, and into the hole or mortise i cut through the crown of thc share o. Its upper end is enlarged to prevent its passing entirely into the niortisc, and

sits up slightly above the crown of the share.

When it is desired to use the plow without the cutter, this key is so constructed as not to project above the share, being only slightly enlarged to prevent its passing entirely into the inortises.

g is the cutter. It passes through the beam 7c, in which it is secured by the key h. It has the notch or inortise o in its lower end, which fits over the upper end of the key f. Its point rests in the notch i', formed in the top of the point e. l is the mold-board, made in usual form, and so that it will fit to the share c. Its front edge laps slightly over the crown of the saddle, and down against the edge of the land-side plate d.

To remove the point c, the cutter g is first removed. Then the key j' is knocked out, when the point is readily withdrawn. The niortise e6 protects the projection e3 from wearing rapidly,while, in turn, said projection supports the point e.

It will be seen that any one or all the parts of the plow may be removed, and new pieces substituted at pleasure.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. rIhe share c, constructed with the flange c2 and triangular projection o3, as and for the purpose set forth.

2.The single plow-point e, provided with the shank e1 and mortises c c6, substantially as set forth.

MLQQ@ have hereunto set my hit-nd this 19th h1-y of Mau-eh, 1874.

JACOB KUENZEL.
